Hall D counting room white board
Contents
Thursday February 2
Past 24 hours
- Maintenance day, tour of Hall D by EIC review people. Beam is back at midnight.
- Harp scans look OK [1]
- Production on diamond. ABU= 2.9h for the day.
Shift Reports
Reports
- HVB current during HV scans (Naomi).
- CDC HVB current vs beam current using this morning's scan (Naomi).
- Current limits and rough estimates of safe HV (Naomi).
- Translation table updated for TAGM (Justin) .
- Swapped HV module for TAGH ch 145 to 168 (Boris).
- Attenuation in different materials (Lubomir).
- Transmission has dropped over the night (Alexandre).
- Trigger rates in 2020 and 2023 (Sasha).
- High Intensity Foil Absorbers (Scot).
- Remote reset for CAEN chassis (Tim and Bobby).
- GlueX Statistics
- PARA 0/90: 16%
- PERP 0/90: 19%
- PARA 45/135: 20%
- PERP 45/135: 18%
- AMO : 25%
Issues
- Start Counter (Beni) We want to confirm that the cables are in the right location.
- Reconstructed Photon Beam Energy Spectrum Deep between 10-11 GeV (Churamani) May be a an issue with timing offset calibrations.
Pending:
- BCM calibration. Accelerator instrumentation group informed us that last BLA calibration was done in 2021 (beside that done Thursday, 01/19/2023? To be confirmed) and recommend Ops to do one at each start of the run period. PD will keep in contact with us on how to proceed.
Plans
- Wait for stable beam delivery for 4 halls. No timelime can be given.
- CDC & FDC response studies at high luminosities. May not happen today, depends on 1uA beam delivery to Hall D.
- Production (300 nA, 2h runs) with cycle:
- 2 runs para(0/90)
- 2 runs perp(0/90)
- 2 runs para(45/135)
- 2 runs perp(45/135)
- 1 run amo (use it to rejuvenate amo reference in CBREM GUI)
Thursday February 3
Past 24 hours
- Recovery from maintenance day. PSPEC troubleshooting. Test runs.
Shift Reports
- Day shift summary
- Swing shift summary
- Owl shift summary
- [ Early Riser shift summary]
Reports
- Power supply trip (Tim, Scot).
- PS magnet at 800A (Eugene).
- ALERT to shift leader: two TAGM columns still at operating Vbias (Richard).
- GlueX Statistics
- PARA 0/90: 16%
- PERP 0/90: 19%
- PARA 45/135: 20%
- PERP 45/135: 18%
- AMO : 25%
Issues
- Pair Spec Magnet Power Supply Flush in morning (Tim) We need to get PSPEC working at 1200Amps.
- Start Counter (Beni) We want to confirm that the cables are in the right location.
- Reconstructed Photon Beam Energy Spectrum Deep between 10-11 GeV (Churamani) May be a an issue with timing offset calibrations.
Pending:
- BCM calibration. Accelerator instrumentation group informed us that last BLA calibration was done in 2021 (beside that done Thursday, 01/19/2023? To be confirmed) and recommend Ops to do one at each start of the run period. PD will keep in contact with us on how to proceed.
Plans
- Citra flush PSPEC power supply.
- Production (300 nA, 2h runs) with cycle:
- 2 runs para(0/90)
- 2 runs perp(0/90)
- 2 runs para(45/135)
- 2 runs perp(45/135)
- 1 run amo (use it to rejuvenate amo reference in CBREM GUI)
